SCREEN. 3

Specification of Letters Patent.

Application filed June 28. 1912.

Serial No. 706,489.

T 0 GE whom it may concern Be it known that I, The E. MolVrLLrAMs, a citizen of the United States, residing at Alva, in the county of Woods and State of C'lrlahoma, have invented new and useful lmprcvcnren s in Screens, of which the following is a specification.

The invention relates to screens, and more Jarticularly to the class of fly screens.

The primary object of the invention is the provision of a screen in which flies on the inside of an inclosure may make their xit throu h the screen at the top thereof but such flies can not gain an entrance tl'icrcthrough from the outside. 7

Another object of the invention is the provision of a screen which is of a construction affording an exit for flies when in an inclosure, yet excluding flies from entering such inclosure, t to construction of the screen being simple, neat in appearance, and in expensive in manufacture.

ll ith these and other objects in view the invention consists in the construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, and pointed out in the claim hereunto appended.

.;.n the drawing z Figure l is a fragmentary plan view of a screen constructed in accordance with the invention. is a similar view looking toward the opposite thereof. Fig. is a top ed e view. Fig. is a vertical in gitudinal sectional view. 5 is a sectional View on the line 55 f the of rig. 1, looking in the direction or arrow.

Similar reference characters send 1 parts throughout views in the drawing.

lteferring to the drawings by numerals, the screen comprises a frame constructed to 'it into a doorway, window casement, or other opening to be screened and includes longitudinal side bars 5 and an end bar 6 at each end of the frame, the said bars being connected together at their ends in any desired manner to provide an open center 7 in the frame. Covering the open center of the frame and secured thereto in any suitable manner is a wire mesh or screen fabric 8, the upper edge of which is bent inwardly indicate corthe several and downwardly as at 9 over spacer blocks 10 which are arranged at intervals on the uppermost end bar *3 at the outer-side thereof and in thi manner exit traps or openings 11 are formed at the upper end of the screen frame, each exit trap or opening being of any desirable length. The inbent portion of the wire mesh or screen fabric 8 is formed with a plurality of exit openings 12 communicating with the trap or openings ll betwe ii the said blocks, so that when the screen is in closed position any flies present in an inclosure can gain an exit by passing upwardly in the traps or openings 11, thence through the exit orifices or openings 12 to the outside of the inclosure. The flies when on the outside will have dithculty in locating the orifices or openings 12 to enter such inclosure therethrough.

The do-wnturned portion 9 of the wire mesh or screen fabric 8 is inturned against the inner edge of the top end rail 6 and is fastened thereto by means of a retaining strip 13, thus concealing the free edge of the fabric throughout the length of the top rail of the frame.

From the foregoing description, taken in connection with the accompanying drawing, it is thought that the construction and operation of the invention will be clearly understood, and therefore, a more extended explanation has been omitted.

What is claimed is The combination with a frame, of a wire netting attached to the side-s and ends of the frame, the said netting being slac tened near the upper end of the frame, blocks arranged in spaced relation to each other in the slackened portion of the netting and having inwardly beveled upper surfaces offsetting and inclining the netting toward the frame contiguous to the upper end thereof, the said netting being provided with holes in its inclined portion between the points of location of the blocks, and a cleat disposed against the outer face of the netting and secured to the blocks.

In testimony whereof I my signature in presence of two witnesses.
